I need help with string lists

[drowsy void]

I'm trying to make an inventory system with the multiple answer prompt, and I want to make it so you can store items on your back and they spawn far away and when you want them back you can select it from the list (that list being your inventory) and it'll reappear in your hand.

I already have the storing away system working, but I cant figure out how to make it permanently add that objects tag name to a list until equipped or removed.

Anyone have any ideas? I was thinking a list variable.

If I used the list variable I believe I could make it a cloud variable which would help alot with saving progress. But I cant figure out how to add that item to the list, it just stays empty.

I've tried list insert and list add. Maybe I should try getting the list add and putting that into a variable?

I'll try that real quick
